摘　　要：牙骨质环是在牙骨质发育过程中形成的持续而有节律的板层状结构,层板之间有生长线间隔,形成状似树的年轮一样明暗相隔的环状。牙骨质环可通过透射电镜、光学显微镜等观察牙齿纵磨片进行计数,其数目可随增龄性或牙周病变发生相应变化。牙骨质环可作为推断年龄的方法,应用于法医齿科学、考古学、人类学等多个领域,具有较为广泛的应用前景。因此本文将从牙骨质环的计数、影响牙骨质环数的因素、牙骨质环的应用、牙骨质环和骨龄推测年龄的方法优劣这4个方面阐述近几年国内外关于牙骨质环推断年龄的研究进展。Tooth cementum annulation is continuous and rhythmic plate layers during the development process of cementum formation. There was interval layer between plate layers, which forms a shape like tree ring as light and dark rings. The number of cementum annulation can be calculated by observing tooth longitudinal grinding using transmission electron microscopy and optical microscope, which is changed along with the age and periodontal disease. Cementum annulation can be used as a method to estimate age. It has been widely applied in many fields, such as forensic dentistry, archaeology, and anthropology. This article will discuss the research progress on the tooth cementum annulation from four aspects: the count of the cementum ring, the factors that affect the number of the cementum, the application of the cementum ring, and the comparison of predicting age by cementum and bone.
